You are correct that there will be plenty of life on the much warmer, greener planet we are heading towards.

Well, probably. There won't be many humans around to verify.

When people say "Save the planet" they generally mean "save the planet as it currently exists", since taking 100 years to make environmental changes that usually take 3000 will have negative effects that outweigh the increase in plant life from a human perspective.
